Task 1.6 Booking Sheet for Grid levels hi Gabriele, Please submit your Part A as well - be sure that it is all complete and correct (in particular, mastudents do not give the collimation error correctly as an error over a distance, or do not complete the levelling reductions and checks). There are a few things to fix in Part B as well. Please see my feedback.

Sum BS column and sum FS column. Calculate misclose. 2. Calculate Rises and Falls. 3. Sum Rise column and sum Fall column. Check that the difference is the same as Sum of BS minus Sum of FS, (misclose). 4. Calculate RLs. Ensure that the difference between first RL and last RL agrees with Sum of BS minus Sum of FS, (misclose). this is incomplete Gabriele. There is a rise figure missing, every figure should have 3 decimal places; plus there must be an error if the sum of rises and sum of falls is not the same- please check all and amend. LPOX, Practical Assessment, CPCCBC4018A, Edition OFFICIAL number 5 1.6 - Sum of BS-0.01 Sum of FS-0.018 Misclose BS -FS = 0 Sum of rise 3.535 of fall = 3.584 Sum of 7 misclose 3.535-3.984 =0.049 17.630-16.655=1.08 there is only one misclose - if your other checks are not the same figure, then you have made mathematical errors
